Those are called the elements of the set.
That is called the average or mean.
a set which has no elements in it is called a null set. example - A={}.
This is called the complement of the set.
It's called an infinite set.
Empty Set
Those are called the elements of the set.
A set is a collection of objects called ELEMENTS OR MEMBERS.
Members.
The difference between joint sets and disjoint sets is the number of elements in common. A disjoint set, in math, does not any elements in common. A joint set must have at least one number in common.
Empty set or null set

a set which has no elements in it is called a null set. example - A={}.
There are various types of sets based on the relationship between their elements. Some common types include: Empty set: A set containing no elements. Singleton set: A set with only one element. Finite set: A set with a countable number of elements. Infinite set: A set with an uncountable number of elements. Subset: A set where all elements are also elements of another set. Proper subset: A subset that is not equal to the original set. Universal set: A set that contains all elements under consideration. Disjoint set: Sets that have no common elements. Power set: A set consisting of all possible subsets of a given set.
This is called the complement of the set.

In mathematics, a finite set is a set that has a finite number of elements. For example, (2,4,6,8,10) is a finite set with five elements. The number of elements of a finite set is a natural number (non-negative integer), and is called the cardinality of the set. A set that is not finite is called infinite. For example, the set of all positive integers is infinite: (1,2,3,4, . . .)
